VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 623,012, dated April 11, 1899.

Application filed December 27,1898- Serial No. 700,385, KNo mokiel.)

have invented certain new and useful Illlprovements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to improvements in vapor-burners using a mixture of vapor and air; and it has for its object to provide a cheap and simple burner which will create a good flame of intense heat when ignited and which is arranged to direct the heat to the part of the oven or stove whereat it is' most needed.

My invention consists in the novel construction and arrangement hereinafter described and claimed.

Reference is had to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure 1 represents a perspective view of my burner and its attachments as applied to a ceramic oven, the said view being taken from a point below the plane of the burner. Fig. 2 represents an enlarged central vertical sectional view of the burner, taken at right angles to Fig. 3; and Fig. 3 is an elevation of the burner as seen from the left in Fig. 2, the dotted lines in said figure indicatin g the adj ustability of the burner for deflecting the flame.

The burner proper iscomposed of a hollow annular base-cup A, having central opening A surrounded above by a flange A. The outer surrounding flange A is provided at opposite points with outwardly-extending tubular radial projections a and a by means of which the said base-cup may be supported, as hereinafter described, and also for the con-. nection of inlet-pipes B and B, which preferably enter said tubular projections, as seen in Fig. 2. The openings through thesetubular projections communicate with the interior of the hollow base-cup from opposite sides, permitting the flow of oil to the said cup from said inlet-pipes from opposite sides, thus insuring a uniform feed and causing the inflowing oil to spread around the said cup in the depression A.

The pipes B and B leading from the same oil-tank (not shown) to the burner in parallel relation the one pipe, as B, must pass half around the said cup A in order to enter the connection A while the other pipe, as B, may enter the connection a? directly. At intervals upon the surrounding flange A within the base-cup A are formed rests a, recessed at a to receive the bottom edge of the hollow shell 0, which fits thereon. By this arrangement of rests a firm seat is provided for the hollow shell 0, and yet the free passage of air is allowed around under the edge of the said shell, as will be readily seen in Fig. 2. An important feature of this arrangement is that the edge of the shell 0 extends downwardly into the base-cup, thus causing the air to dip into the said cup and by coming into close contact with the oil therein create a rapid evaporation of the oil.

A flaring tubular deflector D fits over the central opening A in the base-cup surrounding the flange A. The shell 0 is drawn out into the form of an inverted funnel at its upper end, the suddenly-sloping portion C extending over the flaring rim (Z of the deflectorD, creating a reduced annular passage D around the rim of the said deflector for the upward draft of the mixture of air and oilvapor from the base-cup. The upper extremity of the shell being reduced to a comparatively small neck 0 constitutes the tip of the burner, whereat the escaping air and The burner must be so supported as to per-- mit of a limited tilting to one side or the other upon its supports, the object being to deflect the flame to one side or the other of a central point, as desired, for regulating or varying the intensity of the heat upon the surface of the bottom of the oven, and this is provided for by the arrangement of the two inlet-pipes entering from opposite sides of the base-cup, the burner being capable of a limited swinging movement in a vertical plane upon such inlet-pipes as supports, as will be readily seen. To effect this tilting of the burner, as desired, I may use any suitable means convenient, but as a simple example I have shown in Figs. 1 and 3 an arrangement for this purpose. tom of the oven or frame of the stove and has a screw-threaded end passing near the peripheryofthe burner. Upon the periphery of the burner, preferably upon the base-cup, as shown, at a point midway between the pivotal supports thereof, is formed a bifurcated lug A the bifurcations of which engage in a circumferential groove e of a circular nut E engaging upon the screw-threaded portion of the depending rod E, and thus when the said nut is turned to screw upwardly or downwardly upon saidrod the lug A following the vertical movement of said nut, will rise or fall, as the case may be, tilting the base-cup-A, and consequently the whole burner, correspondingly about its axis of support, as indicated by the dotted lines in Fig. 3. In this manner the flame may be increased and deflected to one side or the other, of the oven as heat is required.

A drip-pan F maybe provldedand suspended beneath the burner by means of hangers F, as shown in dotted lines in Fig. 1.

- The nut E is provided with a series of radial openings in its peripheryfor theinsertion of a pointed instrument for turning said'nut.

, The action of the burner is very simple. The oil enters through the two opposite inlets and flows around within the cup A in a thin film. The air entering the cup A around beneath the lower edge of the shell C passes over this thin film of oil and causes a rapidcombustion thereof. Additional draft is pro- .vided for by the central opening A in the base-cup A.

It will be obvious that my burner is capable of use with almost any sort of an oven of vapor-stove, while itis specially adapted for use with an oven wherein it is required that the A depending rod E is fixed to the bot-" intensity of the heat should be varied at different parts thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a vapor-stove, the combination of a Vertical burner having at the base thereof a vaporizing-cup, abranched feed-pipe com 111 unicating with the opposite sides of the cup and providing a pivotal support therefor, said cup having a flange, and means engaging said flange for turning said burner upon" the pivotal support, substantially as described.

2. In a Vapor-burner, the combination with a base-cup provided with two or more oil-inlets, a depression and a central opening for the admission of air; of a shell in the form of an inverted funnel, the larger end thereof being of less diameter than the base-oup resting within said base-cup, the bottom of said shell when resting in said cup, being below the upper edge of the rim of said base-cup,

whereby downwardly-extendingair-passages are formed between the rim of said base-cup and the edge of said shell; and a hollow de flector within said shell fitting over and concentric with the central draft-opening in said cup, substantially as described.

In a vapor-burner, the combination with a base-cup havlng oil-inlets, said base-cup having a surrounding flange; of a hollow shell in the form of an inverted funnel the larger end whereof is of less diameter than the interior diameter of said flange of the base-cup; projections from the interior of said flange and the bottom of said cup forming rests for the edge of the said larger-end of the said shell; and downwardly-extending air-pas sages between the edge of the said shell and the interior of said flange, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

PETER GRIMM.
